"PPAP (Pen Pineapple Pen Apple Pen)" (Pikatarou)

It's been a while since I discussed a television production... 

Pineapple Murder? was a two-part variety program broadcast on September 20 and 27, starring the idol group Chou Tokimeki Sendenbu. It would have never been appeared on my radar, if not for a tweet that appeared after the first episode was broadcast: it noted that in the credits Shirai Tomoyuki was credited for the mystery plot. I don't know if his announcement had been announced beforehand, due to the interesting set-up of the show. In the program, the six members of Chou Tokimeki Sendenbu are invited to a manor, where they will have a small party to eat a deliciously sweet pineapple, prepared especially by the owner of the manor, who loves the fruit. In fact, his house only has one knife: a pineapple knife, used solely to cut a pineapple. The girls are shown the pineapple, which is kept in a special case. But before they get started on the pineapple, the six get an assignment. At the start of the program, they each were given a special item, like a bluetooth speaker, cat ears and balloons. They now have to go each their own way for ten minutes, making cute selfies and short videos of themselves using those items. Ten minutes later, they all gather on the ground floor and move together to the upstairs sitting room, where the pineapple is waiting for them...

Only they only find the remains of the pineapple scattered on the table: someone has eaten it!

It is then revealed the program up until now was just a ruse to fool five of the six Chou Tokimeki Sendenbu members. One of the girls is the culprit, and while everybody was taking videos and selfies, this culprit ate the pineapple by herself. The television program staff members of course all vouch for each other's alibis, making the six Chou Tokimeki Sendenbu members the only suspects. The girls sit around a table and have to find out who the culprit is, but for some reason, the videos they all took seem to show they all have an alibi for the ten-minute period they were alone. How did the culprit manage to devour the pineapple in the sitting room, while securing an alibi?

 

I have to admit I was kinda surprised at the first episode, as the show started showing floorplans of the mansion and showing where everybody was according to their alibis/videos. It was really set-up as a classic mystery story. But after the second episode was broadcast, I noticed a BlueSky post by Abiko who noted how due to certain limitations like for example budget and the fact it's a variety program starring a idol group, the potential Shirai Tomoyuki holds never comes to fruition, and that is certainly true. The mystery plot we see in Pineapple Murder? is decent at best, following familiar tropes and has the culprit use a trick that is not surprisingly original, but it is properly hinted at with visual clues and things like that.

 Only, you wonder: did you really need Shirai Tomoyuki for that? There is basically nothing here that feels distinct to his work, and that's a shame, for Shirai in particular is an author you'd associate with certain ideas. Okay, I was not expecting anything gross from the solution (again, because we have actual idols as the "characters" here), but still, you do expect something grander from Shirai, and within the show's limitations, it must have been nearly impossible to accomplish something typical of his work.

It is a trick like you often see in the Kindaichi Shounen manga, with a crime having happened while everybody seemingly has an alibi, supported by visual evidence and with people moving around in a building and timestamps and everything, but in a Kindaichi Shounen story, it would only be one element in a larger mystery story. Here it is the main trick, and if you've read a few mystery novels, you'll probably get a pretty good idea of what happened early on. The deduction scene of the Chou Tokimeki Sendenbu members is also relatively short, with most of the second episode being dedicated to the initial examination of all the members' alibis (their videos/selfies), leaving little time for the girls to come up with theories about who the culprit truly is. What we have now feels more like a basis for a larger mystery, and therefore ultimately feels lacking in content.

So I don't think Shirai Tomoyuki fans are missing out on something important if they can't manage to see Pineapple Murder?: it's definitely more something fun for fans of Chou Tokimeki Sendenbu, watching cute girls do cute things. For the die-hard fans: I believe there are two (?) special episodes on Hulu that offer more footage/content beyond the television broadcast. One thing though: the way the girls wrap up their deduction is kinda hilarious and you kinda wonder how it could ever end like that in a real mystery novel.

The Lamp of God

Rationality, that was it. No esoteric mumbo jumbo could fool that fellow. Lord, no! His two feet were planted solidly on God's good earth. 

"The Lamp of God"

Kitayama Takekuni is an author discussed on this blog and that is usually in his role as a writer who specializes in locked room murders with a mechanical trick behind them. If you look at his work in the Danganronpa Kirigiri novels, as well as the Danganronpa and Rain Code games, and of course his Castle series, and the adjecent novels Alphabet-sou Jiken/The Case of Alphabet (2002) and Gettoukan Satsujin Jiken ("The Moonlight Manor Murder Case" 2022), you'll quickly recognize his knack for inventing original and usually bombastic mechanical tricks to his locked room murder situations, almost like he's playing a round of The Incredible Machine. The first installment in the newest Castle book, which started its serialization in the summer, too promises to be another show his inventive mind.

But before that, we have a different kind of impossible mystery to discuss in regards to Kitayama. Late September saw the release of his newest short story collection Kami no Hikari ("The Light of God", 2025), which collects five stories set in different times and about different people, but all connected through one theme: the impossible disappearance of houses. In each of these stories, Kitayama pulls off the magnificent feat of making a whole building, or in one case, a while city disappear without leaving a trace. This might be the very first mystery short story collection that is built completely around this trope in the genre, and in fact, on the obi the editor of the book mentions how the mere suggestion of Kitayama to write such a collection caused them to feel dizzy. But Kitayama certainly managed it, and the result is a fine example of short mystery fiction.

The first story was originally published in 2004 and is titled 1941-nen no Mauser ("A 1941 Mauser") and starts in 1986, in an old bar in Leningrad. A hunter has ventured to visit this bar, named Heroes, because many old veterans who fought in the Second World War still visit this place: our hunter looks up to the military life and hopes he can become a sniper one day, so he hopes to chat a bit with the war veterans. One of the veterans, a former sniper, tells the man about a strange experience he had back in 1941, right in the middle of the war when the Nazis were entering the Soviet Union. The Nazis were also after treasures, and one of those targets was the Glass Room, a "sister" to the Amber Room in the Catherine Palace. As the name would suggest, the Glass Room consisted of beautiful glass and crystal ornaments and was worth a fortune. The Nazis were planning to move the valuables out of the room, but such an operation would take days due to the delicacy of the treasures inside. The Red Army therefore decides to install a two-man sniper unit at a place overlooking the manor faraway: they could easily take out any Nazis attempting to steal the Union's treasure, especially as the Nazis could only transport the treasures out during the day, meaning they don't even have to watch it overnight. The two men brought to an impromptu watchtower, which allows for a good sight on the manor. They spot a Nazi soldier on the rooftop, but don't take any action. When the sun sets, they move to their camp and return to the watchtower the following day, only to find the whole manor missing. Did the Nazis steal the whole building in one night, or something else going on.

This is a great opening story: like the other stories in this volume, it makes great use of the historical setting, both for the atmosphere, but also in terms of how it relates to the mystery, for example when it comes to clueing. While the story is fairly short, Kitayama manages to go over a lot of the "likely" theories that would explain the impossible disappearance and discard them for various reasons, from practicality problems to some "solutions" simply not making any sense to do in the first place. The way Kitayama manages to use a certain clue to both discard a likely theory, but also use it as a definite clue to point to the true solution is really great. The trick itself is grand, as you might expect from Kitayama. It's nuts in terms of how feasible it is in real-life, but it is thematically very fitting. You could easily imagine this trick being used for a "minor" disappearance, but it wouldn't be Kitayama if he didn't use it on something as grand as a whole building.

The title story Kami no Hikari ("The Light of God") goes one step further, and is about the disappearance of a whole city! A not-so-lucky gambler strikes up a conversation with someone at a bar who challenges our gambler, promising to pay out some money if our gambler can come up with a mystery our challenger  can't solve. The gambler himself doesn't even need to know the answer himself, as long as it's a mystery that occured in real-life in relation to himself. The gambler recalls the mysterious experience his grandfather had in 1930: unlike his grandson, his grandfather George was a great gambler: a well-honed sense of memory allowed him to win often at cards and other games and while he had to be careful, he managed to slowly amass enough money to allow him to leave his hometown and try his luck in Las Vegas. He knew the casinos there were careful for people like him who could memorize cards, so his idea was just to make one single strike that could set himself up for life. As he explores the various games, he happens to overhear some high-rollers, who talk about an exclusive invitations-only bus leaving in the early morning for a secret location. George quickly deduces the bus will bring those guests to a special casino with higher stakes and payout rates. He sneaks in the luggage compartment of the bus the following morning and an hour later, he finds himself in a secret city built in a kind of basin. He manages to win some money and decides to steal a bike to get out of town quickly before they realize he's not an invited guest, but soon after he's out of town, his bike breaks down, forcing him to spend the night in a small cabin. When he wakes up the following morning however and looks back.... he finds the whole city missing, and a mysterious light shining down at him. The whole experience makes him feel dizzy. The next moment, he wakes up at the airport, with some pocket money and a ticket for the first flight out of town in his pocket. What happened here?

The title of the story is of course inspired by Ellery Queen's The Lamp of God (another impossible disappearing house story) and the divine light George sees is a vital clue in this story too, but otherwise, there's not much that ties these stories together.This is a story with a great atmosphere though and we also have a Kitayama who's great at snubbing out the solutions you're likely to think of first with both physical evidence and otherwise logical arguments against them. While these stories are all fairly short, usually consisting of 5 segments of which only the middle ones are dedicated to the mystery, and the first and last sections to the framing story, Kitayama always manages to discuss multiple theories, which is pretty impressive. I think the build-up and the atmosphere of this story is great, but depending on your background, the solution might be a bit easier to guess than for the average Japanese reader. I like the story a lot, but certain references did nudge my mind towards a certain theory early on, which proved to be right. Which is a bit of a shame, because it makes me feel like I solved it partially not based on the clues, but just on random knowledge. Which is perhaps a thing here, the solution is definitely better more memorable than the actual path to the solution/the clues.

The third story I already discussed last year, as it was included in the anthology Honkaku-Ou 2024 ("The King of Honkaku 2024"). I refer to that review for my thoughts on the Poe-inspired Mikansei Gekkou - Unfinished moonshine ("Unfinished Moonshine"), but it is cool to see how that story too is part of the "historical setting" theme of this collection.

Fujiiro no Tsuru ("Lavender Cranes") is a story set in three different ages, focusing on three impossible disappearances of buildings. All stories focus on a female member of the Fujiwara clan who possess enigmatic abilities and the young men they protect in their respective ages. In the Heian period, in 1055, while a young male heir of the Fujiwara clan is on the run, a shrine maiden manages to make a whole shrine standing on top of a mountain disappear. In 1999, a young man who lost the ability to play the violin visits the countryside, where a girl preparing for a local festival spirits a shrine on a hill away. And in 2055, a woman of Japanese descent who is a member of the clan running FUJIWARA Industries is suspected to be involved in making a whole military fortress disappear. What binds these three mysteries across the ages? 

A mystery that is somewhat reminiscent of Rurijou Satsujin Jiken (The" Lapis Lazuli Castle” Murder Case): while they don't talk about reincarnation here, the fact we have similar characters appear across multiple ages in a kind of star-crossed destiny manner, and have them deal with similar mysteries of course rings some bells. This is a story, where the atmosphere wins it from the actual trick behind the disappearances: while the trick, which is basically the same across all ages, is one you can understand on a theoretical level, it becomes a bit fantastical when you have to imagine it being used for real. However, because there's a somewhat fantastical atmosphere in the first place, with the story jumping between the ages and presenting a similar disappearances in different contexts, it does work here.

 Synchronicity Serenade is a story originally written for this collection and deals with a reporter who has a recurring dream of an ash-white house, which is then swallowed by the fog and disappears. He mentions it on social media, and is suddenly contacted by a professor, who says he's been having the same dream, and that there are others too who experience the same. He invites the reporter to join his workgroup, as the professor has been researching this phenomenom, but while the reporter initially thinks it has to be fake, he slowly starts to have doubts when the professor shows him a picture of the very house he had been dreaming off. The professor even has an address, so the reporter decides to investigate the house himself to learn why he's been having these dreams, but can he reach an answer?

This is a somewhat different story, as it's set in the modern time and we don't really have an impossible disappearance: it only disappears in the dreams, and the investigation is more focused on why they are having these recurring dreams, and whether the professor is really investigating these dreams or not. The whole story has a somewhat dreamy feeling to it because of that, and while I think the final solution presented is interesting on its own and fits the vibe of the tale, I think the false solution presented earlier feels more in-line with the other stories in this collection.

These were the five stories included in this book, but if you buy your copy of Kami no Hikari via the stores of Kinokuniya within a certain period, you actually get another extra story. At least, your receipt is extended to include an original illustration by Kitayama himself celebrating the release of the book, and a QR-code that leads to another Kitayama story about an impossible disappearance. The story Sayounara, Usagi-dan ("Farewell, Bunny Gang") was originally published in 2011, in issue 49 of the magazine Mysteries! and it was meant to be a farewell to the black bunnies that had been featured on the cover of the magazine for quite some years. Kitayama had been a fan of the illustrations, so he wanted to give them a grand farewell, which involved him reimagining the bunnies as a gang of children without parents, who act as phantom thieves while wearing bunny masks. Hot on their trail are two other children, a sister and a brother, who are great detectives. The tale starts off with the Bunny Gang pulling off another heist succesfully and the narrating bunny gang member announcing their next heist will be his last, as he's too old to remain in the gang. Their next taget turns out to be an entire building, but can the detective siblings prevent such an audacious heist?

This story has been described as a hidden Kitayana masterpiece, and indeed, it's much better than one would expect as a playful farewell story to some magazine mascottes. The story is fairly short, but withi that limited amount of space, Kitayama manages to set-up the whole fictional world of the Bunny Gang, our narrating bunny and the two detective siblings, and also set-up two impossible crimes: one in the in media res opening scene and the main mystery of the disappearing building. The solution of the latter is as grand as Kitayama can get, but it's a bit easy to guess and I have seen another impossible building story that uses the same basic foundation (but with a very different outcome). The first one is the kind of impossible theft you could imagine Lupin the Third of Kaitou KID to pull off and is pretty fun. But I honestly don't understand why this story isn't included in the Kami no Hikari collection properly. While I get it's a bit different in terms of atmosphere, as this is cartoonier than the historical, realistic settings of the stories in the collection and perhaps the story works better with the context of them being Mysteries! mascottes, but still, it's a damn fun story that should be in a proper collected release.

At this point, you can guess what I am going to say here: yes, Kitayama Takekuni's Kami no Hikari is definitely worth a read. It's unique as a collection focusing on disappearing buildings and while some of the solutions to these mysteries feel a bit more fantastical than others, I think these stories are worth a read, as they are all really solid stories, with great set-ups and fantastic atmosphere. If possible, I'd also recommend you to purchase a copy via Kinokuniya in Japan to get the bonus story, though this might only be applicable for physical copies and bought at the physical stores themselves (as I got the code printed as an extension to my receipt).

Mr Brain

"Thoroughly respectable and honest. Not, perhaps, remarkable for brains."

"Murder on the Orient Express"

Now I think about it, it's been easily over a decade since I first read about this book...

Magical Zunou Power!! ("Magical Brain Power!!") was a long-running primetime television quiz program presented by Bandou Eiji and featured a mostly fixed pool of participants of television personalities, some of which are nowadays so huge they have their own television programs like Tokoro George. The program consisted of several rounds of various quizzes with which you could earn 'Brain Power' and of course, the one who has accumulated the most BP at the end, wins that week's episode. The show itself ran from 1990 until 1999, but for the mystery fans, the period that is of interest, is the early days of the show, from 1990 until 1992. For it was during this period, the final round was the Magical Mystery Theater: a short 5-10 minute drama show where a mystery would be presented. While the Magical Mystery Theater segments are all very short, there is "continuity" between them: in the 'series', we follow the private detective Nakatani Shouichi and his niece Natsuko, a college student who acts as her uncle's assistant. The difficulty of each 'story' would be indicated with a Brain Power value, which was also the maximum of points you could earn if you got the answer right (you could be rewarded points for getting it partially correct). After watching the video, the participants would have to guess how it was done or who did it, with an explanation of course. Once everybody had presented their answers, a final, one minute video would follow with the solution. As it's just one round in a quiz program and participants need to be able to briefly explain their solutions, most of these stories are fairly simple in set-up and often revolve around just one single idea, but even so, some of the ideas seen in these segments are actually quite interesting. That is easily explained, when you learn that among those who provided the screenplay writers with the core mystery plots, there are mystery writers like Orihara Ichi, Abiko Takemaru and Shinpo Hirohisa. According to Abiko, Magical Mystery Theater was actually the highest-rated part of the program initially, but even after the overall show started to get higher ratings, this segment's ratings didn't really change accordingly, so it was eventually cancelled.

Shinpo Hirohisa, one of the 'mystery plot' writers, would later revisit some of the scenarios he wrote for the show in Satsujin Trick Gekijou - Nandai Mystery 11 Renpatsu ("Murder Trick Theater - 11 Difficult Mysteries", 1996). The concept of this book is quite interesting. On one hand, it is a book for fans of the original Magical Zunou Power!! corner: Shinpo gives us a glimpse behind the scenes of the Magical Mystery Theater segment, describing what they were going for, how ideas would be discarded and how the segment eventually was cancelled. The eleven stories featured in this pocket are also all followed by an essay on the specific story, noting when the corresponding Magical Mystery Theater segment was broadcast, reception on the quiz, the creative process behind the story/trick etc and what authors/works he drew inspiration from for the trick. This makes this book very informative also for mystery authors I think, as you get an idea of how a mystery writer might develop an idea seen in work X into a different idea, but with the same "foundation."

On the other hand, the eleven stories in this volume are also decidedly not Magical Mystery Theater stories... because obviously, Shinpo doesn't own the show and the characters created for that show. Because of that, he has rewritten all these scenarios with new characters, as well as sometimes changing the plot/trick/clues to accomodate for the book format. It's not the detective Nakatani nor his niece Natsuko who stars in these stories, but we mostly follow Yukiko and Fuyumi, two friends who after graduating haven't quite decided what to with their lives, and so Fuyumi suggest they become detectives, much to Yukiko's shock. They apply at the agency of the detective Mei, but while they don't get hired, they remain on friendly terms with him, occasionally getting him involved in the incidents they end up in, or vice-versa. One important thing to note is that this book also features many original illustrations by Noma Miyuki, the creator of the extremely long-running mystery manga Puzzle Game ☆ High School. They really add a lot of character to this book, especially as it's not 'just' character art, but also depictions of scenes from the stories etc.

Ultimately, these stories were created to be quizzes, so they are by design very straightforward and simple, usually only utilizing one single idea. The book acually retains the "Brain Power" concept of the original show, with each story being worth a number of points, and there's usually also a story section before the solution, that is considered optional: you can skip it to get a high score, or read it to be pushed in the right direction. Note that this optional section isn't just a list of hints, it's a proper part of the story with dialogue and sometimes even story developments.  But because many of them are really just single-idea concepts that you may have seen elsewhere already, I am not going to discuss each story this time.

The first story, Hito wo Kuu Heya ("The Room That Eats People") is the story that first made me aware of this book: it was mentioned in a mook on locked room murder mysteries edited by Arisugawa, being mentioned in a long list of recommended short locked room/impossible crime stories. In this story, we first see Fuyumi and Natsuko visit the detective agency of Mei, who decides to test the two girls with an excercise in a stake-out. He puts his assistant Dan in a room, and tells Yukiko and Fuyumi to keep an eye on the room, making sure his assistant doesn't escape. Fuyuko is told to watch the door from the corridor, while Yukiko is brought outside and told to watch the window from the street. After a hour, the two are to swap places, and after another hour, Yukiko is to enter the room and apprehend Dan. The two girls do as told, and two hours pass by without anything suspicious happening in the room. But when Yukiko enters the room, she finds the room empty. How did Dan escape? The trick behind Dan disappearing from a room under observation is pretty simple and it's likely you will have seen a variation of the same idea before, but Shinpo does a great job at planting the clues that point to that solution, and I would have loved to have seen the Magical Mystery Theater segment. In the essay, Shinpo mentions how Miyabe Miyuki told him how she really liked the tale, only for Shinpo to reveal he actually got the idea from a Miyabe story, transforming it in a way so even she herself didn't recognize it!

In Shide no Tabi ni mo Kinen Satsuei ("Taking Photographs Even When On Your Way to the Afterlife"), the comedian Hashiba Kenzou wants Mei to help him, because he received a letter from an unknown sender, saying "she wants to return her key, but also talk with him on the 7th, when he's filming at a cliff: Hashiba suspects it's one of his three exes with a key to his apartment, but he finds the letter very creepy, especially as she apparently knows his work schedule and wants to meet him at a cliff. Mei declines the job because he is not a bodyguard, nor does he like the playboy comedian, but then Hashiba is indeed murdered, having been pushed off the cliff.  Miraculously, someone managed to take a picture of Hashiba as he was falling, which provides a vital clue to finding out which of three women pushed him, but how? Once again, the solution is very simple, but I love how it does make very good use of the original visual format: while the illustration by Noma does wonders to support this story in the novel format, I imagine it would have felt more intuitive as an acted segment on Magical Mystery Theater.

In Totemo Kimyou na Yuukai ("A Very Curious Abduction"), Mei tells Fuyumi the tale of the abduction of Yuuka, the daughter of a client, with whom he often played shogi. Mei was present when the father received the call, instructing him to go to a coin locker at the station with a stash of money. Mei is sent instead, and in the coin locker, he receives further instructions to make a phone call to a certain number from the public payphone in a nearby park. The number given goes to Osaka, but the man answering the call says that while he does know Yuuka, he doesn't know anything about an abduction. Because of that, the money deal with the kidnapper seems to have failed, and Yuuka is soon found murdered in a nearby park. Police investigation show that the man answering the phone call in fact did have a perfect alibi for killing Yuuka, but how could have kidnapped Yuuka and killed her in Tokyo, if he answered a phone call in Osaka? The trick itself I find remarkable because it is so much a trick that only works in the period this story was created: it wouldn't fly at all now, because society has changed so much and we don't use certain things anymore. But that is why I really liked this story: it is a simple, but clever trick, but it would also be very understandable to people who don't have any interest in mystery fiction, because it used an object people would know in the nineties in an original manner, but also a manner which would make you go "Aha!" because it's actually so simple. There are a few other stories that have a similar vibe, using everyday life objects/customs of the early nineties which feel out-of-date/not obvious anymore, like in Satsujin yo, Kinou ni Kaere ("Murder, Go Back to Yesterday"), where an alibi is shot down by pointing out a certain object isn't where it should be, but which nobody in Japan nowadays would really think of.

Satsujin Trick Gekijou isn't really a must-read for mystery fans, though I would definitely recommend it to those who used to watch Magical Zunou Power!! as the behind-the-scenes essays are really interesting (and I say that as someone who hadn't even seen the show!). And of course, I do have an interest in mystery shows that are formally divided in problem and solution sections, so being able to experience the show in some manner, even if in a different format, is something I appreciate a lot. While most of the stories in this book are very simple, focusing on single-idea tricks that you likely have seen in other mystery-themed quizzes, or other mystery stories already, I find the presentation of this book very consistent: Noma Miyuki's illustrations do some of the lifting, but Shinpo's writing is easy, and while the main tricks are pretty simple overall, he does a very consistent job of properly clewing everything, making these stories a bit more involving than just single-concept mystery quizzes.

Accident by Design

"De architectura"  

 

Firmness, commidity and delight 

"On Architecture"

I wanted to say it'd be cool to have a mystery set in an Escher building, but then I remembered I already read one....

Kenchiku Shizai (2001), which also carries the English title The Builded Dead on the cover, is the 11th winner of the Ayukawa Tetsuya Award and is the "professional" debut of author Monzen Noriyuki, though he had previously self-published a different novel (interestingly enough, that book got a professional release later on). Monzen studied architecture in university, which is all too clear in his debut novel, which originally was sent in to the Ayukawa Tetsuya Award committee under the title The Building That Eats People. The book is narrated by Miyamura Tatsuya, a man in his thirties who's having a long holiday in Nagoya: after attending to a friend's wedding there, he decided to stay at his uncle and aunt's place, which is also an udon restaurant. His cousin Yuuichi is still in high school and (should be) studying for his university entrance exams, which explains why he is still up late at night. One evening, Yuuichi spots a light source moving about on one of the floors of the construction site across the street: a large new building is being erected there, but work has been paused for a few days due to the obon holiday season. His childhood friend Momose, whose father is a subcontractor for the construction site and working in their own workshop to meet a deadline, also sees the light. The two keep an eye on the building, and eventually confide to Tatsuya about the intruder. They decide to sneak inside the construction site to see what's happening. Fortunately, all the foundational work is already done, with the load-bearing walls/support pillars and the stairs finished, allowing them to move about relatively safely. They spot a shadowy figure and chase them into a meeting room on the second floor, but the figure locks the door behind them. Momose is sent to watch the windows outside, while Tatsuya and Yuuichi try to get into the room, which they eventually do by breaking through one of the non-bearing walls. However, they find nobody inside, and the windows are locked from the inside. The trio are puzzled by the disappearance of the figure, and Yuuichi and Momose stay up all night to see if they can spot the figure escaping the site, but it appears the shadow has really just disappeared into thin air.

The following day, they contact Kumote, the on-site supervisor, as he's the only one in authority whom Yuuichi knows the address of, and who hasn't gone somewhere travelling during the holiday season. They have another look in the half-finished building together, while Yuuichi explains what happened the previous night, and suggesting the figure might have hidden themselves inside the walls, but Kumote explains the process of constructing the various walls in the building and how it'd be impossible to either hide into a load-bearing wall, or how they would've instantly spotted someone in one of the non-finished non-bearing walls. The mystery is left unsolved by these men, but then the police becomes involved in a rather surprising manner. The president of the contruction company has gone missing, and the previous day, a cut-off finger had been sent to his home. His secretary is missing too, and one of her body parts was also sent to her home. This also happened to a teacher, who seems to have no connection to the president or the secretary. It also turns out a day worker with no fixed address had sneaked into the construction site on the same night as Yuuichi, Momose and Tatsuya did, hoping to stay in the half-finished building during the holiday, knowing it would be empty. However, he claims he fled the scene when he found three bodies cut up in pieces there, The police suspects those are the bodies of the people they are looking for, but where are the bodies? It seems obvious to assume they are somewhere in the building, but the workers themselves, with their expertise of actually constructing the walls/ceilings/floors seem very sceptical of the possibility of that, as most of the construction involving concrete/mortar was already finished and you'd instantly know if something was 'added' later on. However, when more murders occur at the construction site, it seems clear the building is indeed the crux of this mystery and it is Kumote, with his knowledge of building a house, who tackles this challenge.

A challenge indeed, but not for the reason you might expect at first. The book immediately makes an impression when you open it, as you'll find the volume opens with very detailed floor plans of the five-storey building around which most of the mystery revolves. And while having each floor printed on its own page isn't that uncommon (especially not in Japanese mysteries), the fact each floor is in fact printed on tracing paper is highly unusual! It is here Monzen already shows his familiarity with building design and construction, as tracing paper is used extensively in those fields and it is used here in the book like it is used 'in real life', to show exactly how each of the floors overlap, making you aware of where walls on different floors overlap or not and how corridors/rooms are different between floors. This of course seems to suggest something incredibly clever will be done with this... but I'd say 90% of the justification of this insert, is simply to be authentic, and not per se to faciliate the mystery. Which is a shame, because I was genuinely surprised by these pages when I first opened the book.

In a way, this experience with the very first pages of the book perfectly symbolizes my experience with the whole work. Throughout the book, Monzen really shows he's an expert on the topic of designing and constructing a building and you can feel his enthusiasm throughout the book as he builds the mystery, but it's also his knowledge that really limits the possibilities behind the book. A lot of the mystery revolves around what the murderer did with the three bodies seen by the homeless worker that night: Yuuichi and Momose didn't see anyone carrying three people's worth of body parts out of the building and because the police didn't manage to find the bodies in open spots in the building under construction, the most "mystery-tropey" solution would of course be that the bodies are buried in the walls, but Kumote quickly rejects that possibility by giving lectures on how buildings like these are actually constructed, and with most of the supporting concrete 'parts' of the building set and finished long ago and the non-bearing walls/floors/ceilings simply not lending themselves for hiding spots. Via Kumote, we learn Monzen has obviously given a lot of thought about whether the body-in-the-wall trick could work realistically without anyone noticing, and he gives several detailed reasons why he thinks that's unlikely.

So that leaves the question, where did the bodies in fact go? And how did the dark figure Yuuichi, Momose and Takuya chased, disappear from the locked meeting room? And later in the book, we have another murder on the roof, and all the suspects seem to have a good alibi for this murder, as the time of the crime can be estimated by the fact the murderer left their footprints on a part of the flooring that hadn't set completely yet at that time. While this book thus has as few impossible mysteries (a locked room disappearance even).... I have to admit I basically found all the solutions a bit disappointing. Ironically, this was not because Monzen didn't do his homework on the topic: in fact, it is the exact opposite. He was so thorough in sticking to actual architectural details and realism, the tricks he ends up using just come over as too... plain? While Kenchiku Shizai is definitely a honkaku mystery novel where they talk about locked room mysteries and impossible disappearances and tropes like hiding bodies in the walls, Monzen ends up with far too few options for truly surprising solutions to his own mysteries, and you end up feeling a bit... indifferent to the reveals of what really happened. I can agree his takes would work in real-life at a real construction site, but that doesn't make those solutions really exciting or anything, they just seem like more... realistic and practical versions of tricks I have seen used in more unrealistic, but infinitely more amusing manners, or at least presented with more energy and surprise. I think if you're into architecture, this book can be quite interesting, especially after seeing the more fantastical ways in which buildings are used in Japanese mystery fiction, but for me, it just felt lacking because of the reality.

That said, there are also really brilliant points that help support the mystery. The motive behind the death of one of the victims is really the kind of ideas I love to see in mystery fiction: it strangely fits the realistic angle of Monzen in this book despite also being pretty crazy. The same regarding another late murder: there is a very specific reason for the victim to be found with a knife in his back, which is also brilliantly realistic and at the same time so out-of-there. It's moments like these that really make an impression especially because they make a perversion of the rather realistic look at the construction industry and they really did help elevate my experience with the book.

 On one hand, I can really appreciate the research Monzen poured into this book, and it results in a book that is really educative about how a building is built, knowledge which of course comes in handy in a genre with a lot of quirky buildings with weird gimmicks. But on the other hand, Kenchiku Shizai's main mysteries are all resolved with rather plain solutions because of Monzen is bound by this realism. It's when he dares to go a bit beyond those limits, when the book feels the most memorable. I wouldn't call this book a complete disappointment though. I am aware there are more books with Kumote as the detective (and architecture/building construction as the theme), and I am curious to see what else Monzen can do with his knowledge, so I will probably try more of his books, so I will likely return to him in the future.

Original Japanese title(s): 門前典之『建築屍材』

Diagnosis of Murder

Primum non nocere

First, do not harm

I like the style of the illustrations on this cover, though I wish it was a bit more obvious which character is supposed to be who in the book. And before I had a good look at the cover at full size, I only knew it from a small thumbnail, and I thought the art would be similar to Tezuka Osamu's art, which... isn't really the case now I see it at full size.

EDS Kinkyuu Suiri Kaiketsuin, which also has the English title EDS Emergency Detective Services on the cover, is a rather interesting anthology of mystery writers, all using the same original setting: in the near future, Japan has erected the Emergency Detective Services, which functions like the emergency department of a hospital: people with medical emergencies that require a detective are brought here. The hospital has a large of number of specialist departments, from doctors handling children and animals to specialists who 'cure' impossible crimes and other curious mysteries. The doctors at this hospital are referred to Holmeses, while their assistants are called Watsons. This book contains stories by Ishimochi Asami, Kagami Masayuki, Kuroda Kenji, Komori Kentarou, Takada Takafumi, Tsukatou Hajime, Torikai Hiu, Matsuo Yumi and Nikaidou Reito, who is likely the planner of this large project as he also wrote the preface. All the stories in this book are set on the same day (the twenty-fourth of December), and each of these writers takes on one of the many departments of the EDS. Have a look at this hospital, where for some characters it's just another day at work, while for others it's a literal matter of life of death.

I first learned about the existence of this volume when I read The Uncollected Stories of Masayuki Kagami, which ironically included Kagami Masayuki's contribution to this volume, The Uncanny Deductions Department (which I won't discuss here, as I refer to that review for my thoughts on it). I say ironically, because obviously, his story was already collected in EDS Kinkyuu Suiri Kaiketsuin. Anyway, I wasn't aware of it at the time, but later I learned Kagami's story was just of many set at the EDS. Which also brings me to one other point I wanted to discuss before moving on to the individual departments/stories. When I read Kagami's story, I noticed how the scenes were all time-stamped, to give you a feeling of the "emergency" going in, but it actually had another function. While Kinkyuu Suiri Kaiketsuin features nine authors, writing about ten different departments, the stories are all set on the same day in the same hospital... so they decided to put all the scenes of all the stories in chronological order. So you are not reading story 1, and then story 2, and story 3, but it's scene 1 of story 1, then scene 1 of story 5, then scene 1 of story 4, etc. You are constantly jumping between stories, and while there are moments this feeling of "real-time"-ness is used for example for cameos between the stories, it's not actually necessary to read these stories like this: to be honest, they read a lot easier as seperate stories, instead of constantly being interrupted by other stories, so if you want to, you could just as well just read all the stories individually. The book's formatting and design is done really well by the way, with "tabs" on the edge of the page like it were a file folder, marking each department/story, so you can easily skip to the next part ("tab") of the story you want to read. 

Ishimochi Asami's story is set in the Inchoushitsu  ("Director's Office"), where the director of the EDS is visited by Minai Nanase, whose father used to work in the Poison Department of the EDS, until he died under mysterious circumstances last year: a John Doe who appeared to have been in a fire was brought in one night, but there were too few staff that night: the triage Watson couldn't find the right "Holmes" (specialist) to help the man, until the Holmes Minai happened to pass by and decided he'd try his hand. They failed in saving their patient, unfortunately, and later on the Holmes Minai summoned the Watson in charge to his office. Yelling and fighting followed, and when other people entered the office, they found both men dead: the Watson had been stabbed with a pair of scissors, which were being held by the dead Minai, who had apparently hit his head on the corner of a desk. It appeared Minai had stabbed the Watson, only to be pushed away himself, hitting his head on the desk fatally. The whole deal was hushed up, but now daughter Nanase has returned, demanding to know the real truth, because she can't believe her father would have killed the Watson for whatever reason. She threatens the director by showing she has planted a camera on Sayuri, the young daughter of the chief receptionist, who always at the hospital. Nanase has gifted Sayuri a Santa hat (with camera) and a bag with something that might "go off" if Nanase clicks her pen, forcing the director to give her all the infomation about the death of her father, hoping to clear his name. This is a pretty thrilling story playing out in the director's office, even though nobody in the hospital itself knows what is going there. The mystery regarding why Minai and the Watson ended up dead last year is pretty good, with subtle clues pointing to a well-hidden explanation for why the two men ended up fighting and killing each other. This story by the way also mentions a Holmes called Ukai, who hails from Ikagawa City... Author Ishimochi debuted together with Higashigawa Tokuya via publisher Kobunsha's Kappa-One program, which is why they know each other pretty well, and probably why Ishimochi decided to insert a cameo of Higashigawa's character here.

Nikaidou Reito is responsibile for two storylines, but both of them are very light. The Uketsuke ("Reception") story features more like intermezzos between the various stories, featuring cameos of characters from all the stories. The Shouni Suirika ("Children's Deductions Department") story stars six-year old Shibugaki, a guest Holmes who narrates like he's a hardboiled detective. He solves a few minor mysteries fellow children bring him, and the main mystery for him revolves around two children who have an argument about a place both of them supposedly visited, both calling the other a liar. The solution is basically just a trivia thing, so not really interesting as a puzzle.

Kuroda Kenji's Sports Suirika ("Sports Deductions Department") has a far more interesting puzzle. Banba, A father who coaches his own son, a promising swimming athlete, has a rather unique problem. His son is always losing to Hino Shouta, so Banba decided to adminster doping to Hino, in the hopes of getting him disqualified. Banba knew Hino's diet is closely monitered and that he always has to drink a certain energy drink before going in the pool, so his plan involved administering a forbidden drug in one of his drinks. Hino receives a month's supply each month, and is of course quite protective of his energy drink, but last month, Hino, Banba's son and other swimmers were all training together at a facility, and Banba found an opportunity to sneak into Hino's room, where he had stashed his newly delivered supply of his drinks. Banba had prepared a special gadget which allowed him to reseal a bottle, making it impossible for anyone to see the difference between an originally-sealed bottle, and the one he opened. And indeed, Hino broke a swimming record when the big competition came around, so everything seemed to go according to plan. Until... Banba heard no news of Hino being caught for doping. Was everyone covering up for Hino? Banba thus wants the Holmes to how Hino could've used Banba's doped drink without being caught, as he is absolutely sure Hino couldn't have known he had been doped. An interesting puzzle of the kind you don't often see in mystery fiction (a doped drink, i.e. not poison) and I also really like the way Kuroda used a hidden fact, which you can deduce based on the hints, to explain what happened to Banba's doped drink and how it was used by Hino. I'm always a fan of these kinds of stories, where you don't deduce the "main" mystery straight on, but it becomes a two-level type of mystery. 

Takada Takafumi's story is set at the Rekishi Suirika ("Historical Deductions Department"), fitting as Takada's mainly known for his Q.E.D. historical mystery novels. This story revolves around a dying message, where the victim was holding on to a page from a Japanese historical poem, which should point to one of three suspects for the murder. Like all good dying message stories, this story points at several possible interpretations of the message, all pointing to different suspects, until the Holmes comes with the correct solution, but this story does what is always risky with dying message stories: the final, correct solution fails to be really convincing as the final one, as in, it fails in convincing the reader this last solution is the actual correct interpretation and that the others are wrong. In reality, the 'wrong' possibilities feel as valid as the real one, which undermines the whole dying message.

Another disappointment for me was Torikai Hiu's Doubutsu Suirika ("The Animal Deductions Department"), where the Holmes is asked to save a dog who was poisoned, the third victim in a series of dog violence, one of them even fatal. The story is basically a missing link story (why is someone targetting these dogs?), but the solution is not really surprising or entertaining as mystery fiction, with the link feeling somewhat out of place and also over-telegraphed. This idea would perhaps have fared better if this was only the first part of a mystery, with more building on it/as part of a larger narrative. But on its own, it feels underwhelming.

Komori Kentarou's Gaikokujin Suirika ("Foreigner Deductions Department") deals with mysteries involving foreigners, with specialists from various cultures present. In this story, a Japanese man is accussed of the murder on his American wife Lucy, who was set to inherit her father's business, which would have greatly upset her father's business partner. Husband was working on the building project America Village in D City, with the husband acting as a liason for the city as he speaks English. Lucy was visiting Japan for the first time and after staying at her brother and sister-in-laws, she was given a ticket on the express train to Osaka to reunite with her husband. However, she did not arrive by the express train she was given tickets for, and the following day, she was found murdered near the hotel of the husband. The husband had since said a few things that seemed to indicate he knew more about her death than he was willing to admit, which has made him the prime suspect in the murder, even though Lucy's father's business partner, who was also in Japan, had a good motive for wanting Lucy dead, even though he has a perfect alibi for when Lucy would've arrived in Osaka. This story has both brilliant ideas, and very wrong concepts. The book presents great reasons for why the husband's a suspect, and these reasons are closely related to the mystery genre, as it involves linguistic misdirection (only in this case, it was the husband who accidentally said something that put suspicion on him), but then the trick behind the 'alibi trick' behind Lucy's death follows, which is a bit troublesome. For there's a brilliant piece of misdirection, one I truly love and which I think is incredibly well thought of, but it is immediately followed by an idea that hinges on a complete misunderstanding on the part of author Komori about how a certain thing works, and it makes the whole deal fail. For that... is not how it works. So that trick wouldn't work. Which is a shame, for the first part of the idea is really good and a good example of the mystery trick based on cultural differences.

Tsukatou Hajime's Fukanou Suirika ("Impossible Deductions Department") starts when two men are brought in: one is unconscious, the other has been strangled to death and in such a strong manner hand marks can still be seen around the throat of the victim. It turns out both men were found in the same storehouse, which was locked from the inside and the only key was also found inside. This seems to point to the unconscious man (Rokujou Eiichi) as the strangler of the other man. The Rokujous are a fashion mongul led by Eiichi's father, and the victim was a freelance writer who was visiting the Rokujous to interview them on the upcoming fashion show. Both Eiichi and the victim had vanished from the sights of the other people in the house after a fight, until they were found in the locked storehouse, one of them dead. Eiichi's brother however doesn't believe his brother killed the man, despite the fact the only key was found inside the locked storehouse and the victim clearly having been strangled by hand only shortly before he was discovered in the locked storehouse. This is a mechanical locked room as we have come to expect from Tsukatou, though I wouldn't consider it one of his best. While he sketches an interesting problem with a locked room murder trick that involves strangling, the solution to the locked room is rather simplistic, and you'd wonder whether it'd really fool the police for long as it seems a bit unbelievable it would work the way it is described here. So not one of my favorite Tsukatou tales.

Matsuo Yumi's Joseika ("Women's Deductions Department") has one of the more interesting stories in the tale: Migishi, the Holmes of this department, is visited by a pregnant woman who comes with a strange tale. Last week, the client, who will soon give birth to her first baby, was on her way to the Q University Hospital when she noticed a new gynecology clinic had opened nearby. As the place was less crowded than Q University Hospital, she decided to have her check-up there, and she was quite pleased with how things went, so today (two weeks later), she visited again, only to find the place was closed and everything had been removed, and there wasn't even a notice or anything explaining why it had closed. It is odd a clinic would close so suddenly, so Migishi takes the case, planning to call some acquintances in the medical world to see if they heard about anything about this, but to her surprise another client arrives directly after the first left, with the exact same story. What happened to this gynecology clinic to have it disappear so suddenly? While this is a variation on a well-known type of mystery story, I think Matsuo did a great job at spinning this into her own original version and at the same time, working this into the EDS theme of the Emergency Detective Services being a hospital too. To be honest, a lot of the other stories do extremely little with the hospital theme, so this one really stands out, which is surprising to me, as this was the one author I hadn't read yet before! I guess it helps Matsuo is best known for her Balloon Town series, about a town where only pregnant women live...

EDS Kinkyuu Suiri Kaiketsuin is a book that has a cool premise and few cool ideas, but it is definitely not a work where the total is greater than the sum of things. Not all writers truly make use of the unique EDS setting besides scenes of people being brought into the hospital, and while the intermezzos do their best to glue the stories together, as well as the device of having all the scenes of all stories printed chronologically, it often doesn't really feel like one coherent work of fiction. Having more of a running thread between all of them would have helped, or using a smaller cast and having Holmeses appear more prominently in each other's stories. Some of the stories are good mystery stories on their own, and others simply don't know what to do with the (relatively) little amount of pages each story gets alloted to them. So not a must-read as a whole, though some of the stories are worth a read.

Seven Dead

"Men have called me mad; but the question is not yet settled."

"Eleonora" 

Eight locked room murders in the last review of the eighth month of the year!

It was Mitsumura Shitsuri who was the defendant in the trial in Japan that created the Golden Age of Locked Room Murders in Japan: she was accused of committing a murder, but the police were not able to figure out how the murderer could've committed and then left the crime scene, as it was found locked from the inside. Shitsuri was succesfully defended with the argument that an unsolved locked room mystery was as strong as any alibi: the prosecution being incapable of proving how anyone could've committed the murder and escape a locked room in essence meant every single person on the planet had an alibi. If it was impossible for anyone, why would it be possible for specifically the defendant? This created a rage among would-be murderers to commit their crimes in locked rooms, for that seemed like a perfect defense. This was the perfect breeding ground for locked room murder specialists, both within the police and among private detectives, but also among criminals, where locked room murder consultants became a lucrative business.

Shitsuri's classmate Kasumi this finds himself dragged to the mountains by his childhood friend Yuzuki, as she's looking for New Nessie in the Tama River. the two end up lost in the mountains a little time before dusk, but are fortunately found by Monokaki Camembert ("his mother was a foreigner"), who lives in the nearby Village of Eight Boxes. Because there is no other place nearby where the two can stay, Camembert suggests they come with him to the village and stay in the inn there. To the great surprise of both Kasumi and Yuzuki, they vind the Village of Eight Boxes is actually located inside a gigantic cave, that can only be accessed via a long tunnel, which is guarded during the day and of which the gate is closed during the night. The villages is called like this, because the houses in this village are built like smooth lacquer boxes (you don't need pointy roofs with a drainage system inside a cave where it never rains!). It takes some time for Kasumi to realize Monokaki Camembert is in fact one of the members of the Monokaki Clan: a family of locked room murder mystery authors, Father Fuichirou was the foremost writer of locked room mysteries in Japan, but he recently passed away, leaving a huge fortune to his nine children, who have followed in their father's footsteps, or are trying to. Each of his children specialize in a different kind of locked room mystery novel, like medical locked room mysteries, historical ones, or even hardboiled ones. The family all live here in the village, though their manor is physically seperated from the rest of the village via a chasm in the cave. Kasumi also learns a local festival is going to start that very evening, and it last for about a week, and during that time, it is not allowed for anyone to leave the village, or else an evil spirit will kill them.

When the festival starts however, one of the Monokaki daughters is seen to be killed by a masked figure, but they quickly disappear with the corpse. However, after Camembert and Kasumi have gone to the Monokaki manor to inform the rest of the family about the murder, the bridge that crosses the chasm in the village is blown up, leaving the people in the manor trapped on their side of the cave. Meanwhile, the other villagers decide it might be better to call the police, but they find the lines have been cut, and when one brave villager, despite the local belief telling him not to, tries to venture beyond the tunnel in order to fetch the police, a gate suddenly closes off the tunnel, and the villager suddenly bursts out in flames, even though nobody was near him. Yuzuki, who is still in the village, discovers the body of the disappearing Monokaki daughter in one of the houses, but to the surprise of both her and the local constable, the house is locked from the inside. And as they scramble about, they stumble upon more dead bodies of members of the Monokaki family inside locked rooms. Fortunately, Yuzuki runs into two women in the village who can solve these crimes: not only is the author Oujou Teika, Japan's young queen of the locked room mystery, staying at the same inn as Yuzuki, it turns out Shitsuri too is working here as a part-time help. Can they solve the many locked room murders occuring the Village of Eight Boxes both on this side of the cave, as well as inside the Monokaki Manor in Kamosaki Danro's Misshitsu Henai Jidaino Satsujin - Tozasareta Mura to Yattsu no Trick (2024), which also bears the English title The Murder in the Fetishistic Age of Locked Rooms: The Closed Village and the Eight Tricks.

This is the third book in Kamosaki's series on the Golden Age of Locked Rooms and The Age of Frenzy of Locked Rooms and by now, the titles have become more and more ridiculous, but I guess that is also the point, which is also exemplified by the fact we are now in the fetishistic age of locked rooms, where the locked room mystery almost takes on a perverted form. For in a way, that is exactly what this book does. The first book featured six main locked room murder mysteries (or otherwise impossible situations), the second had seven of them, and now this third entry has no less than eight of them! And while this was already a problem with the second book, the fact Kamosaki wants to cover so many locked room murder situations in a limited amount of pages, means that on the whole, these books are more about quantitty than quality. That is not to say the ideas behind the locked rooms are bad on their own per se, but there is basically not set-up each time: they stumble upon a murder scene, Kamosaki has just enough space to actually describe how the scene looks like, and perhaps one character might suggest a wrong solution, but then we have Shitsuri who has one look at the crime scene and she can suddenly solve the whole thing, even if the trick is insanely complex and involving multiple steps. There is no real feeling of catharsis when she solves the mysteries, because not enough time is used to actually make it feel like a proper mystery, nor do you feel satisfied by the "logical pay-off" of the solution, because the solution is suddenly sprung upon the reader. So while sometimes the idea behind the locked room mystery can be cool and memorable on its own, it's the execution that lacks, because every murder feels like a descrete point with next to no connection to the other murders.

To be honest, it started out really promising, as the first two murders are the ones that are actually thematically connected, with an interesting conundrum arising when the solutions to these rooms are first suggested. The problem that comes up because of how they are solved is interesting and creates a very fun logical brainteaser. The false solutions proposed here are also far more interesting than the ones we see later, if we see them at all, and it feels like Kamosaki focused a lot of attention to these murders. I think these were among my favorites too in the book, as the synergy shown during this part of the book is what really shows what I think this series should do: have it be meaningful there are so many locked room murders in a closed circle situation, instead of just throwing a bunch of them on a pile. Two others I also liked a lot: one involving the victim having been hanged in a building, but the security system shows nobody entered the building the last 24 hours, neither the victim nor any murderer! The trick might become a bit obvious if I explain a specific point regarding how they found the victim, but the trick itself is original. Another one is one of the most horrifying locked room murder tricks I've ever come across in mystery fiction, and involves the victim having been decapitated in a room while their body had been tied to a table in the room: the mechanics behind how the murderer pulled this trick off are just too terrible to even to think about, and devilishl clever.

The others vary a lot in quality. The combustion murder of the villager for example involves the most crudest of clues, and the "okay, this is silly, but not the good kind of silly" trick has your eyes rolling. There are more murder situations later in the book that are also incredbily silly in concept, but at least those are so silly they become good, even if the execution can be faulted. Others feel more like showpieces of random scientific trivia, while one also feels like a Professor Layton puzzle more than anything. The last 'big' mystery that is solved involves some Queenian logic, which I can always appreciate and something I also noticed in the second volume, but on the whole, Kamosaki is definitely someone who ultimately just wants to show off a lot of locked room murders, that are created via mechanical tricks. He however often does the bare minimum of actually making them relevant to the story or each other. Characters may or may not have a single line of dialogue before they are killed, there's no build in tension because every event feels so seperate from each other and once you're done with the book, you'll have forgotten half of the locked rooms already, because they were handled in such a brief and uninvolved manner.

But again, that is what makes this books a little bit fetishistic, as the title itself also says: the book only exists to flaunder with all the locked room murder situations Kamosaki could come up with, and some of them are really creative on a basic, fundamental level. As you can guess, this also comes back to the motive behind the murders on all these locked room murder mystery authors, and that part I really liked, Interestingly, it reminded me of a certain novel by Kitayama Takekuni, who is also an author who specializes in mechanically constructed locked room murder mysteries, so it's funny how Kamosaki also arrives at a similar "conclusion" regarding locked room murder fiction.

Misshitsu Henai Jidaino Satsujin - Tozasareta Mura to Yattsu no Trick is, unsurprisingly, more of the same after the previous two books. More locked room murders, but beyond that, it's not really that different from them, and while I can recommend this book too to lovers of locked room mysteries, because some of the murders here are really worth reading (no matter how silly they can be at times), but like with the previous books, you do have to admit Kamosaki is mainly about showcasing all these ideas, and they do feel lacking in the way they form a cohesive narrative, and how they are actually presented as "mystery" fiction with clues and a process of logic leading to the solution.

Original Japanese title(s): 鴨崎暖炉『密室偏愛時代の殺人 閉ざされた村と八つのトリック』

Battle of the Humungonauts

"Way I see it, the beast can only be a completely-new and as-yet-undiscovered monster, and as the beast discoverer, I have decided to call it a "humungonaut" from the Latin term for "big and hairy space traveller."

"Scooby Doo: Mystery Incorporated"

Yep, this cover rocks!

The first kaiju attacked Japan in the fifties, and since then, the world has been regularly been under siege by a variety of these gigantic monstrous beasts. Nobody knows where they come from, but they can appear very suddenly from the sky, ground or the sea and attack people and the cities they live in indiscriminately. As it's been many decades since First Impact, humans however have adapted to this new reality. Japan, being the first country to have to deal with kaiju, has been a forerunner when it comes to developing defence systems against kaiju, and most countries have now adopted their three-tier defense system: the first line of defense are the Active Detection Units, which are actively searching for indications a kaiju may appear, wherever it may come from. They for example monitor movements out in the ocean, but also investigate local rumors about strange happenings, for that too may be an omen a kaiju will soon appear. Once the appearance of a kaiju has been confirmed, responsibility is passed over to the Planning Units: they identify a kaiju, and if applicable, pull up all the data from past encounters to determine their weak points and the best way to fight them, and they calculate the route and when they will arrive on Japanese soil. Once a kaiju hits land, control is passed over to the Eradication Units, who by then should be standing by at the estimated landing point with the necessary artillery to fend off the kaiju attack. It's this system that has allowed Japan to fight off kaiju succesfully, and by now, people have actually become accustomed to kaiju attacks, and the government is even aiming for a 0 deaths by kaiju quotum.

Iwato Satomi is a Chief Planner: whereas there are Planning Units all across Japan, ready to react to a kaiju appearing nearby, Chief Planners are not tied to any specific unit, and are flown all across Japan to take charge of such units when necessary, assisted by local planners who have more knowledge about the specific region and politics. While it may seem a gigantic monster attacking a city might make any other issue trivial, it turns out people will remain people, and even when a kaiju is approaching, people will still commit murder. During one operation, in which a whole evacuated city was demolished by a kaiju, the corpse of a man is found. However, it turns out the man was killed by a human, not a kaiju. Iwato is visited by Inspector Funamura Shuuji of the Special Investigation Unit, who deals with these kaiju-related crimes, and the two work together to figure out who committed a murder during a kaiju attack in Ookura Takahiro's short story collection Kaijuu Satsujin Sousa: Senmetsu Tokku no Seijaku ("The Kaiju Murder Investigations: Silence in the Special Eradication Zone", 2023).

Ookura Takahiro is an author of mainly mystery, both on paper as well as for the small and silver screen: he for example often writes screenplays for the Detective Conan anime. He however also has an interest in tokusatsu and kaiju productions: he has written novelizations of Godzilla productions, as well as screenplays for Ultraman Max, and one of his best-known Detective Conan anime original stories indeed involved a kaiju. So it was only a matter of time before he would write a detective story featuring kaiju, right?

And you can definitely feel his love for the genre right from the start, for I'd argue it's the world building in the four stories collected in this collection that is the most memorable aspect: Ookura has built a very believable world where people have gotten used to dealing with kaiju. The defense organization comes across as very realistic as Ookura has thought out a lot of the details of how each units works, their responsibilities and even the political tensions between them, and we see glimpses of how national politics and other industries have changed, or are at least influenced by kaiju. You could easily imagine these scenes in full-on kaiju media, and it's here where the book really shines best.

The notion of having mystery stories set in a world where kaiju exist and regularly attack the country is of course really exciting, and really entices the imagination: imagine someone using a kaiju as a murder weapon! A kaiju used for a locked room murder trick! As a motive! It is why I do have to say that overall, I was a bit disappointed to learn Ookura mostly uses the kaiju, and the kaiju attacks as a backdrop for the murders. Take for example the title story Senmetsu Tokku no Seijaku: Iwato is dealing with a kaiju with acute hearing which reacts to unnatural noises, so the Planning Unit orders a silent eradication zone: they try to lure the kaiju to a place where the Eradication Unit can deal with it with an aircraft, while everything else in the area is "shut down". However, on its way to the slaughterhouse, the kaiju seems to react to a noise: it turns out a pistol had been shot, and eventually, they find a man who was shot in the vicinity of the kaiju. And yeah, it's interesting it was the kaiju which brought them on the trail of the victim, and ultimately, we do learn the victim was here for a reason tied to the kaiju, but the kaiju itself isn't really connected to the murder beyond this. The mystery itself revolves around the victim and his reasons for being where he was, making the kaiju feel like just a plot device to introduce the victim and who is then pushed to the background. Even though you'd want the kaiju to be the main dish!

The opening story, Fuusha wa Tomaranakatta ("The Wind Turbines Didn't Stop"), was more interesting in that regard: Iwato is dealing with a kaiju that had appeared in the past, and based on its behavior then, surmises it reacts to the sounds of wind mills. The kaiju is heading for a spot where the Eradication Unit can easily deal with it, but nearby is a city with wind turbines, so Iwato uses her connections to order the city council to have all wind turbines stopped. To her great surprise, one section doesn't stop its turbines, and as they fear, the kaiju heads for that spot and destroys it. While the Eradication Unit manages to defeat the beast, one victim is found among the debris. However, it turns out he was murdered by a human, and not simply crushed by the kaiju. Here we have a much more interesting investigation, as the victim turns out to be Tozuka, who was an important man in an electric company which was pretty aggressive in buying out land from the local populace, and he's been personally sued for that. But why was he still in the city even though an evacuation order had been issued and why didn't the wind turbines stop? Here we have a much more intricately designed mystery, and while a lot of the story does revolve around shady politics and a 'bigger-than-life conspiracy', the core whodunnit part of the mystery is properly clued, and at least the kaiju is more integrated into the mystery.

The third story, Koujinko Satsujin Jiken ("The Lake Koujin Murders"), on the other hand is basically nearly pulp. Iwato is sent to investigate the disappearence of several persons around Lake Koujin: this is usually the sign of a land-based kaiju eating people, and a Chief of an Active Detection unit had actually gone there to check up on these signs, but he too disappeared. The frustrating aspect however is that land-based kaiju are believed to not exist in Japan anymore, making it political unwise for the higher-ups to send a whole unit to investigate it. So now Iwato is "privately" visiting Lake Koujin, where she's staying at a small inn where a few other visitors are staying, but one of them was actually a contact for the disappearing Active Detection unit chief, so Iwato tries to learn more about his disappearance from him. But that night, a loud noise wakes up everyone... except for her contact, and when they check up on him in his room, he's found murdered. But which of the other guests killed him? This story I didn't like that much, as here the kaiju is only made relevant very late in the story. The murder itself has an interesting clue: on its own it's a bit obvious, but the deduction leading up to the realization that was a clue made it mentally more challenging. 

You may have noticed I haven't written much about Inspector Funamura by the way: he appears and disappears throughout the story, and is presented as a rather mysterious police detective who often already knows that is going on and is very practical in his dealings with crime, but also needs Iwato's expertise at times, so while he seldom gives away all his cards, he does help Iwato figure out things for herself. He's also the man of action in this series, which again make these stories feel more grounded in tokusatsu tradition than the mystery genre.

The bunko/pocket version of this book includes a prequel short story, Kaiju Chaser, which depicts a younger Iwato as she tries to identify a certain kaiju, but this is more an action story than a mystery one and it's really short too.

So I'm a bit torn on Kaijuu Satsujin Sousa: Senmetsu Tokku no Seijaku. It's clearly written by someone who loves the kaiju and tokusatsu genres, and it can be immensely amusing when read as such a book, and the mystery plots are also decent enough most of the time, but I still can't help but think Ookura could have incorporated the kaiju more closely to the mystery plots, using them more as active tools rather than as backdrops around which these murders take place. A second volume has been released too, so I hope the kaiju are more involved with the murders there.

Panic on Gull Island

Open here I flung the shutter, when, with many a flirt and flutter,

In there stepped a stately Raven of the saintly days of yore;

    Not the least obeisance made he; not a minute stopped or stayed he;

    But, with mien of lord or lady, perched above my chamber door—

Perched upon a bust of Pallas just above my chamber door—

            Perched, and sat, and nothing more.
"The Raven"

Suddenly craving fried chicken...

Iwaido Yasumi is a student at Teiou University who hopes to impress his lecturer Uehara Kanon, a beautiful, cool-headed woman who teaches his cultural anthropology class. He ends up writing a paper that is actually quite impressive, so much so she summons him to her office. Not because she's become romantically interested in him, but to make sure he didn't plagiarize his essay. While Yasumi tries more than once to woe Kanon, she brushes his advances and informs him that Professor Kirimura Satoru, the most influential professor at their faculty, has also read his thesis and has ordered Yasumi to be added to an upcoming fieldwork trip. Kirimura will lead a team, including Kanon and Yasumi, to Torikui Island, a solitary island that is technically part of Japan, but which has been deemed "off-limits" for decades. Centuries ago, it was used as an island to send sentenced criminals to, even though there were indigenous inhabitants too, and with time, a unique culture developed, seperating the island in two distinct clans, one of the indigenous people and one of the descendents of the sentenced criminals. The main staple food on the island is surprisingly not fish, but birds of prey, and the two clans are named after their preferred food: the Eagle clan and the Raven clan. Because sentenced criminals were usually branded by having a part of their body mutilated, the people on the island also developed a unique sense of "beauty": when an islander becomes an adult, a part of their body is amputated to mark them as as a full adult person: the Eagle clan people mutilate their face (eyes or ears removed), while the Raven have limbs removed. Long ago, a person rumored to be related to a very important and esteemed bloodline was banished to the island and this Man in the Iron Mask-esque figure became feared and respected as a living god on the island named the Bird Demon. Because of their bloodline, the Japanese authorities also occasionally sent supplies to the island to ensure the people there could live, despite it being completely cut off from the rest of Japan and it was forbidden for people from the mainland to go to Torikui Island, or vice-versa. Some decades ago, Takaoka Jinichi, professor at Teiou University, stayed for months at the island to do research on the local culture, and it is the only source of information on the island.

Kirimura Satoru, who studied under Takaoka, also visited the island in the past, but now returns for a new research trip, because recently, Inou Nao, the young daughter of the island's only doctor, escaped the island in search for help. Inou Kaoruko hails from the mainland, but was stationed at the island to serve as the only medical expert. Nao was raised on the island, but has now violated the island rules to look for help: she claims that the last few years, the peace on the island has been visibly crumbling apart: there are only about thirty people left on the island, with few children, and both the Eagle and Raven clans are on the way to extinction. This has caused a very strong rift between the two clans, and it could go wrong anytime. While usually, the Japanese authorities does not allow for visits to Torikui Island, Kanon reveals to Yasumi there's a hidden agenda to their research: the government wants to use Torikui Island as an experiment to see how people will act in a declining society that is on the verge of falling apart. 

To Yasumi's big disappointment, he learns on the day they are travelling to the island that Kanon isn't allowed to go, because Kirimura Satoru deems her an academic rival and doesn't want her around. Other people in the team however include Kirimura's half-sister (an academic too), a researcher attached to the university and two government "observers". Nao is also brought along, though in disguise, because she violated the local rules. When they arrive at the island by yacht, they are "welcomed" by the Eagle clan, though some of them seem to blame Kirimura for the fall of the island, as everything started to slowly crumble after his visit many years ago. They learn the Bird Demon has disappeared from the island, and because this figure of authority is gone, the rivalry between the Eagle and Raven clans has only worsened. In fact, the two clans are so against each other the houses on the island are in fact built to alternate between a house of the Eagle and Raven clan, so they can all keep an eye on each other like a panopticon. The fieldwork team settles for the night, but Kirimura goes out for a stroll, while Yasumi calls Kanon to report on the on-goings on the island. When Yasumi remembers he left his phone charger in the boat, he returns to the beach to the yacht, but he finds Nao stabbed to dead on the beach. But for some reason, only Nao's own footprints are found in the sand, and there are no signs of footprints left by her killer. At that same moment, he receives a message from Kirimura Misaki, who summons the rest of the team to her, because she found her own brother murdered. These two deaths however are just the starting sign for a full breakdown of Torikui Island in Mori Akimaro's Setsudantou no Satsuriku Riron (2024), or as the cover also says: The Genocide Theories in the Mutilation Island.

This was definitely a book I picked because of the crazy premise and alluring title: an island where people willing mutilate themselves because they think it's beautiful? A closed circle mystery set inn isolated and small society doomed to fail and end in genocide? I had never read anything by Mori Akimaro before, but this description really sounded alluring to me, especially with its focus on anthropology.

Once I got started reading however, it did take me a lot of time to get used to the protagonist, and even at the end, I never learned to like him. He's constantly trying to be witty and hitting on Kanon, his lecturer, and after a while it really got old. There's some mystery revolving around how he wrote his essay even though he himself even admits he doesn't quite understand how he could've written such an impressive work, but that is hardly fairly clewed: while it has huge implications for him, it's not really that well integrated with the main mystery of the murders that occur on the island, and it felt like two completely different ideas that don't work together. But add to that the fact he's really obnoxious every time he talks to Kanon (he's constantly keeping her up-to-date on what has happened on the island), and it's really a shame he's the character we're constantly following in this narrative...

Once we arrive on the island however, we do get the highlight of the book: Torikui Island, its inhabitants and the unique culture they have. Mori does a great job at setting the scene and explaining how the people on the island developed their own cultures, based on their food culture (eating predatory birds, as you obviously can't have cattle on a small island like that) and the fact most of them are descended in some way from mutilated criminals, giving them a warped sense of beauty: all the adults miss a body part, and the children aren't seen as full humans because they still have all their body parts. The rivalry between the clans creates the unique situation where the houses are laid out like a panopticon around the main square, and so you instantly get a kind of impossible crime set-up, because everyone is watching each other. That is how the book also initially sets things up, as while Kirimura Satoru and Nao end up dead, the islanders are quite sure none of them are the murderer, and are more suspicious of the fieldwork team members. We also have the wildcard Kaoruko, the mother of Nao, who does live on the island, but has never been fully accepted by either clan. While we initially are 'treated' to the double murder of Kirimura and Nao, we soon see the native inhabitants be killed too in all kinds of manners: while these situations are seldom 'impossible' or pure mysteries on their own (i.e. killed in a way anyone could've done it), that doesn't make their deaths less interesting: the slow downfall of the island society is truly a sight to behold, and at the same time, Mori manages to use the very unique island culture to create a few very ingenous and crafty situations that could only occur here. The use of anthropology to create tricks in mystery is something I very much like (see for example the use of religious concepts to create mysteries in the Toujou Genya series), and The Genocide Theories in the Mutilation Island very much succeeds in that aspect: a lot happens in this book, and surprisingly enough, those happenings could really only happen here, because this is such a weird place, and some of the mysteries the reader will be treated to, are extremely memorable cause of that. And when Yasumi isn't trying to interrupt the discussions by hitting on Kanon, there are actually quite interesting musings on anthropological topics that pertain to this novel, from the consumption of birds to views on beauty etc.

But there is a caveat. A pretty big one too. Don't be reading this for the impossible crimes. There are a few impossible situations, from the no-footprints-in-the-sand situation at the beginning, to Kirimura also being killed in a place that was basically observed, but the solution to these mysteries is really outrageous. I guess you could say it was hinted at, but not in a sane manner, and nothing about the story leading up to the reveal seemed to even suggest this would be such an insane mystery novel, so to me, it really felt like it came out of nowhere. I loved the way Torikui Island was developed as a very strange, yet weirdly convincing place, but Mori certainly didn't manage to pull the same thing off in regards to his impossible crimes in this novel. In a way, this could be seen as a 'so-silly-it's-brilliant' type of explanation, but I find the juxtaposition with the more serious depiction of the island's culture from an anthropological POV not smooth, though your mileage may vary there.

So in the end, I do think Setsudantou no Satsuriku Riron is a really cool mystery novel, with an absolutely banger of a setting which is used in clever ways for some of the mysteries, but I wouldn't be reading this solely for the impossible crimes, and you do need to be aware it's a bit weird when it comes to the solution, despite the rather heavy themes of the events on the island. Still, a very memorable novel which I am likely not going to forget soon.
